White ink is less desirable to use for tattoos than black ink because it fades more quickly and requires more frequent touch-ups. While white ink tattoos have certain perceived benefits, they also bring other aesthetic risks that should be carefully considered by anyone planning on getting one.
The main benefit of white ink tattoos is the glowing effect they give off under a black light, as well as their perceived subtlety under normal light. However, white ink tattoos produce good quality results on a narrower spectrum of skin types. The visual effect produced by white ink tattooing is less forgiving than black ink. People with freckles or redder skin tones may not achieve a successful result from white ink tattooing. Also, in many cases of white ink tattooing, the ink fades quickly - and the result is a strange, faded-looking image.
There is a skin disease said to produce an effect similar to some of the less desirable results of white ink tattooing called dermatographia. Dermatographia is a condition where skin infection, emotional upset and certain medications can cause swelling, inflammation, raised red lines, hive-like welts and itching. White ink looks beautiful when used by a professional to highlight a tattooed image, but tattooing in white ink alone brings several risks that a person should consider carefully before going under the needle.
